For example, the stowage assembly may include a fastener or clip, such as handle stowage clip 128, which may be disposed on or in the housing, such as on the front clamshell housing element 105 as shown. Alternately, or in addition, the stowage assembly may include a handle stowage cup 126, which may be disposed on the axle 124 or on other elements of pipe inspection system 100. For example, as show in FIG. 3, pull-handle 108 may be stowed in stowage cup 126 and secured using stowage clip 128 in a stowage configuration.

A lifting mechanism, such as lifting handle 112, may be coupled to the clamshell housing 102, such as by using a pair of mount supports 110 or other attachment mechanisms, such as screws, adhesives, and the like. One or more cord wraps, such as a right cord wrap 111 and a left cord wrap 113 as shown, may be disposed on mount supports 110 and/or elsewhere on the outer housing assembly for stowing a system connection cable (not shown in FIG. 1), which may connect the pipe inspection system 100 to a camera control unit, monitor (not shown in FIG. 1), power supply, computing system, or other device or system.

An access port, such as access port 406, may be included on one or both the front and back sides of an outer housing to allow an operator to access a stored push-cable for deployment and retraction. In addition, accessories such as cameras that are mounted to the push-cable may be accessed for deployment through access port 406, thereby allowing for storage of the camera or other accessory on or internal to the outer housing assembly. In this configuration where the access port 406 is formed on the front of housing 102, a camera may be deployed through a port such as port 310 (as shown in FIG. 3).

Embodiments of pipe inspection systems may include fixed or detachable wheel assemblies. For example, in some embodiments, a fixed wheel assembly may be used, wherein the wheel attachment elements, such as axles, mounting bosses, and the like, are permanently fixed to or molded or formed into the outer housing assembly or to another structure such as a frame.

Alternately, in some embodiments, a detachable wheel assembly may be used to provide for removal of the wheel assembly and/or addition of a wheel assembly to a non-wheeled pipe inspection system (such as, for example, a pipe inspection system lacking wheels and/or a push-/pull-handle). For example, in one embodiment, detachable wheel assembly embodiment 114 (further described subsequently with respect to FIG. 8) may be mounted to the lower portion of the front clamshell housing element 105, using, for example, one or more axle caps, such as a left axle cap 116 and a right axle cap 118. Wheel assembly 114 may include an axle, such as axle 124, to provide support for one or more wheels, such as a left wheel 120 and right wheel 122. The axle 124 may be disposed within an axle tube 800 (as shown in FIG. 8), which may be enclosed by a shield or sleeve, such as axle tube sleeve 125, which may be disposed between the left axle cap 116 and the right axle cap 118, for providing wear and abrasion protection to system 100. The wheel assembly 114 may be mounted using connectors such as screws, bolts, rods, etc., that pass through the housing via vents 106.

FIG. 2 is a rear perspective view illustrating additional details of the wheeled pipe inspection system embodiment 100. Pipe inspection system embodiments may include one or more feet or pedestal elements for supporting and protecting the system during use or storage. For example, in an exemplary embodiment, an upper right rear foot 200 and an upper left rear foot 202 may be disposed on or within the outer housing assembly, such as on a surface of rear clamshell housing 104. Alternately, or in addition, one or more pedestal elements, such as rear left lower foot 206 and rear right lower foot 204, front right lower foot 208, and front left lower foot 210 (as shown in FIG. 4), may be disposed at the bottom surface of clamshell housing 102.

A system connector cable for carrying signals such as analog or digital electrical or optical signals, battery data signals, and/or electrical power, such as system connector cable 212, may be coupled to a removable slip-ring assembly 214, which may be disposed in an opening in the outer housing assembly, such as an opening in the center of rear clamshell housing 104. One or more sliding latches, such as an upper right sliding latch 216, a middle right sliding latch 218, and a lower right sliding latch 220, may be used for locking the mated halves (front clamshell housing element 105 and rear clamshell housing 104) of clamshell housing 102. Other mechanisms may alternately be used to couple elements of the outer housing assembly in various embodiments.

Referring to FIG. 3, details of wheeled pipe inspection system embodiment 100, in a configuration where pull-handle 108 is stowed, are illustrated. As noted previously, pull-handle 108 may be seated into the handle stowage cup 126 and retained by the handle stowage clip 128.

The pull-handle 108 may include a handle mounting alignment mechanism for aligning pull-handle positioning and restraining pull-handle motion. The housing assembly may include a seating mechanism for securing the pull-handle during use, while readily allowing removal for stowage. For example, the handle mounting alignment mechanism may include an alignment pin 300 on pull-handle 108, which, when deployed, may drop into a seating mechanism, such as formed groove 302 on the handle accessory mount 109, for preventing rotation of the pull-handle 108. The formed groove 302 may be backed by a molded insert 303. In other embodiments, alternate alignment mechanisms, such as keyed slots, hinges, or other alignment mechanisms known or developed in the art may be used.

In an exemplary embodiment, a spring-loaded toggle 304 may move a lower pin (not shown in FIG. 3) into a lower hole 306 on the pull-handle 108 when it is fully inserted, to prevent the handle 108 from slipping upward when pulled, as well as preventing rotation. When the spring-loaded toggle 304 is pressed in, the lower pin (not shown) is withdrawn, allowing the pull-handle 108 to be removed from the groove 302 in the handle accessory mount 109.

One or more sliding latches, such as right upper sliding latch 216, right middle sliding latch 218, and/or right lower sliding latch 220 (see FIG. 2) may be used for locking the halves of the clamshell housing 102 together. A push-cable, which may be spooled on a drum (not shown), which may be coupled to a pipe-inspection camera 308, may be fed from the inside of the outer clamshell housing 102 through an opening, such as a cable feed opening 310, which may be lined with a formed wear insert 312, or other friction-reduction mechanism, such as a bearing to aid in deploying and retracting the push cable.

A camera stowage mechanism, such as camera stowage clip 316, may be disposed on the outer housing, such as on a plastic front plate 314, which may be mounted on the front surface of front clamshell housing element 105. The pipe-inspection camera 308 may be stored under the camera stowage clip 316 when not in use and/or elsewhere on system 100.

FIG. 4 illustrates details of wheeled pipe inspection system embodiment 100, shown in a front perspective view. A front bumper 400, which may be constructed of rubber or other similar or equivalent materials, may be disposed centrally below the cable feed opening 310 on a raised bumper section 402, which may be a molded feature of the front plate 314. In combination with the front feet 208 and 210, the front bumper 400 may protect the front surface from abrasion, fluid or dirt infiltration, and/or other hazards from contact with the ground.

The wheel assembly 114 may be mounted to the front clamshell housing element 105 with the left axle cap 116 and the right axle cap 118, which may be attached with fasteners, such as screws 404 to a mounting plate (not shown in FIG. 4). An access port or opening 406 may be formed in the housing to allow an operator to manually lead the camera 308 (as shown in FIG. 3) through the cable feed opening 310 when preparing the system 100 for use.

Referring to FIG. 5, a rear view of the wheeled pipe inspection system embodiment 100 is illustrated. In an exemplary embodiment, the system connector cable 212 may emerge from the removable slip-ring assembly 214. The system connector cable 212 may alternately be longer than shown in FIG. 5, and excess system cable may be stowed using the right cord wrap 111 and the left cord wrap 113. The slip-ring assembly 214 may be constructed in accordance with embodiments described in, for example, U.S. patent application Ser. No. 12/704,808, entitled PIPE INSPECTION SYSTEM WITH REPLACEABLE CABLE STORAGE DRUM, filed Feb. 12, 2010, the entire content of which is incorporated by reference herein. Non-skid material, such as textured rubber or other similar material, may be disposed on the surface of one or more feet, such as rear left lower foot 206, rear right lower foot 204, rear left upper foot 202 and rear right upper foot 200 to prevent slippage and protect the surface of housing 102 when operated in a horizontal orientation (as shown in, for example, FIG. 6).

Referring to FIG. 6, a side view illustrates details of the wheeled pipe inspection system embodiment 100 in a horizontal orientation, laid down or resting on the ground or another surface 650. In an exemplary embodiment, the pipe inspection system 100 may be lowered to a horizontal orientation using the pull-handle 108. In this orientation, the pipe inspection system is supported on feet or pedestal elements, such as the rear left lower foot 206, rear right lower foot 204 (shown in FIG. 5), rear left upper foot 202 and the rear right upper foot 200, which may be configured to provide clearance for the system connector cable 212 to lead out to a system monitor and/or camera control unit (not shown) between the ground 650 and the housing 102. Corresponding latches (not shown) may be used on the other side of the outer housing in a similar fashion.

Operating the pipe inspection system 100 in a horizontal orientation may provide advantages such as stability when the system is used on various terrains, such as for example, sloped roofs or irregular terrain, and may provide other advantages such as ease of operator use or viewing of images or other information shown on displays or monitors of the pipe inspection system 100 (see FIG. 4). The camera 308 and the associated push-cable 606 in this orientation may be payed out from the upper face of the housing 102, and the camera 308 and/or attached push-cable may be accessed for retrieval or paying out via access window 406 (not shown), which may be done from the top of system 100 in the orientation shown in FIG. 6.

One or more latches, such as a left upper sliding latch 600, a left middle sliding latch 602, and a left lower sliding latch 604 may be used to secure the halves of the clamshell housing 102. Other attachment mechanisms may alternately be used to secure elements of the outer housing in different embodiments.

Turning to FIG. 7, a bottom view of the wheeled pipe inspection system embodiment 100 illustrates additional details. In an exemplary embodiment, a central hinge 700 may be used for joining the front clamshell housing element 105 and the rear clamshell housing 104, which may be disposed on the bottom surface of clamshell housing 102, for allowing the clamshell housing 102 (as shown in FIGS. 1-3, and 6) to be opened to access a replaceable cable storage drum (not shown), or for cleaning, maintenance, and repair. The left lower sliding latch 604 and right lower sliding latch 220 (in addition to middle and upper sliding latches on right and left sides) may be used for securing and/or releasing the halves of clamshell housing 102.

FIG. 8 is an enlarged exploded view illustrating details of detachable wheel assembly embodiment 114. In an exemplary embodiment, axle 124 may be disposed within an axle tube 800, which in turn may be shielded by the axle tube sleeve 125. A pair of shock isolators, such as axle tube isolators 814, may be disposed at the ends of axle tube 800 for providing shock dampening at each end.

Wheel assembly embodiment 114 may include very high bond (VHB) tape segments 816 positioned between the axle tube 800 and the left axle mounting block 806, and/or between the axle tube 800 and the right axle mounting block 808. When compressed in assembly, the VHB tape segments 816 may act to prevent any lateral displacement of the axle tube 800. One or more washers, such as washers 804, may be positioned between axle tube isolators 814 and the wheels 120 and 122, which may be mounted to the ends of axle 124. The pull-handle stowage cup 126 may be disposed at the left end of the axle tube 800.

When assembled, the wheel assembly 114 may be mounted by seating the left axle cap 116 and the right axle cap 118 over the axle tube 800. One or more fasteners, such as retaining screws 404, may be used for securing left axle cap 116 and right axle cap 118 to retaining plates (not shown in FIG. 8), such that the wheel assembly 114 may be tightly secured to the front clamshell housing element 105 (as shown in FIG. 1). For example, screws 404 may be lead through formed holes in the left axle cap 116 and right axle cap 118, and through mating holes in left axle mounting block 806 and right axle mounting block 808, and then through one of the vent openings such as, for example, vents 106 (as shown in FIG. 1), where they may then be attached to or through the retaining plates. In some embodiments, quick disconnection mechanisms, such as screws with handles or wing nuts, latching mechanisms, or other quick-release attachment mechanisms may be used to further reduce the time and effort required to remove or attach the wheel assembly.

FIG. 9 is a front perspective exploded view of a front half assembly embodiment 908, illustrating details of an attachment mechanism of the wheel assembly 114 and a front clamshell housing element 105.

The pull-handle 108 and related attachment elements, as well as the wheel assembly 114 and related attachment elements, may be used to modify the commercially available housing to include wheels and a pull-handle as shown.

In an exemplary embodiment, one or more retaining plates, such as a pair of handle accessory mount retaining plates 900, a right axle assembly retaining plate 902, a left axle assembly retaining plate 904, and/or a handle stowage clip retaining plate 906, may be used for attaching various components to the front clamshell housing element 105. For example, the wheel assembly 114 may mate to the rear half assembly 908 with the right axle assembly retaining plate 902 and the left axle assembly retaining plate 904. The handle stowage clip 128 may similarly be secured by fasteners or other connectors, such as screws 104, pins, bolts, and the like, leading through one or more of vents 106 and attaching to the handle stowage clip retaining plate 906. Other quick-release attachment mechanisms may alternately be used to secure the wheel assembly 114 to the outer housing assembly.

Referring now to FIG. 10, additional embodiments of attachment details of the wheel assembly and pull-handle are illustrated. For example, the wheel assembly 114 may be retained by attachment hardware, such as screws 404, which connect the right axle assembly retaining plate 902 and the left axle assembly retaining plate 904 to the right axle mounting block 808 and the left axle mounting block 806 respectively, passing through apertures or vents 106 on the front clamshell housing element 105. The handle accessory mount 109 may be similarly attached by the two handle accessory mount retaining plates 900. The handle stowage clip 128 may be similarly attached with the handle stowage clip retaining plate 906. In an exemplary embodiment, the pull-handle and wheel assembly are attached through the outer housing assembly with hardware positioned within existing openings or cavities in the outer housing assembly, thereby allowing simple retrofit of non-wheeled pipe inspection systems.

FIG. 11 is an enlarged plan view of details of a rear half clamshell assembly embodiment 1104, illustrating an attachment mechanism for components mounted to the inside of rear clamshell housing 104. In an exemplary embodiment, one or more feet, such as rear left upper foot 202 and the rear right upper foot 200, may be secured to the rear clamshell housing 104 by a pair of corresponding retaining plates, such as, for example, an upper left foot retaining plate 1100 and an upper right foot retaining plate 1102.

The attachment mechanisms described in the preceding examples may provide flexibility for configuring pipe inspection systems, such as wheeled pipe inspection system 100, with various accessories and components. For example, a mounting deck for a laptop or monitor used for processing images captured by a pipe-inspection camera 308 (as shown in FIG. 3) attached to a push-cable 606 (as shown in FIG. 6) may be attached in a fashion similar to the pull-handle and wheel assembly, such as using mounting hardware passing through vents such as vent 106.

Referring to FIG. 12, details of an alternative embodiment of a pipe inspection system 1200 are illustrated. In an exemplary embodiment, system 1200 may include a portable monitor and camera control device, such as portable camera control unit (CCU) 1202, which may include one or more computer processors or processing elements, camera control and monitoring elements, such as displays, keypads or other input or control mechanisms, data transmission and storage components, as well as other computer control, processing, and storage elements, and may be incorporated with a wheeled pipe inspection system, such as pipe inspection system embodiment 100, to facilitate simultaneous transport of both the CCU 1202 and the pipe inspection system 100.

For example, a portable CCU 1202, which may include a built-in monitor or display device, such as an LCD panel (not shown), along with one or more processing elements and associated electronics components may be removably attached to the external surface of the rear clamshell housing 104 of the pipe inspection system 100 with a mounting element, such as a purpose-designed CCU mounting block 1204, which may be configured for retaining the handle of the portable CCU 1202 with one or more fasteners or clips, such as spring-loaded clip 1206. The CCU mounting block 1204 may be mounted to the rear clamshell housing 104 with a retaining plate (not shown in FIG. 12), which may be similar to those shown in the preceding examples (such as, for example, retaining plates 900, 902, 904, and 906 as shown in FIGS. 9 and 10). In operation, the closed portable CCU 1202 may be secured by the spring-loaded clip 1206, and supported by the CCU mounting block 1204. The portable CCU 1202 may be detached from the clamshell housing, such as clamshell housing 102 shown in FIGS. 1-4, and 6, for set up and use by depressing the spring-loaded clip 1206.

FIGS. 28 and 29 illustrate flow charts describing two exemplary processes for enabling a computing device to view content from a smart cable storage drum, and to control certain aspects of a smart cable storage drum. One of skill in the art will appreciate various alternative processes for enabling such a computing device to view content from various resources in a system, including one or more inspection devices, other computing devices, and remote databases. Having access to content from various system resources enables a user of the computing device to enrich content received from an inspection device, correlate content from multiple resources, and better coordinate the efforts of one or more users in the system. Moreover, having access to content using one or more networks permits one or more users on the network(s) to view, manipulate, control the capture of, and manage the distribution of content from various locations and at various times.

For example, an electronic computing device, such as a personal computer, tablet device, smart phone, or other computing device, may access inspection data from a cable storage drum via a wired or wireless network (e.g., LAN, WLAN, cellular network, Internet, etc.), which may include a network hub disposed on or within the portable inspection device, such as within a hub of the cable storage drum or elsewhere in the cable storage drum. The computing device may also access related data from another system resource (e.g., another cable storage drum or inspection device, another computing device, or a backend database). Similarly, the cable storage drum may access the related data from the same resources. The computing device may then display the inspection data and/or the related data. A user at the computing device may also edit the displayed data and/or create data, and may distribute those edits and create data to the other resources in the system. The user may also control, over the network, any of the networked resources. Similarly, other users may also control any of the networked resources.

FIG. 30 illustrates details of an embodiment 3000 of a data transfer system between a battery and battery shoe disposed on or within the portable inspection system and a wireless transceiver disposed therein, such as in the hub or elsewhere in the inspection system. A battery 3050, which may be a standard rechargeable or single use battery or, in an exemplary embodiment, an intelligent or Lucid rechargeable battery such as described in U.S. patent application Ser. No. 13/532,721, entitled MODULAR BATTERY PACK APPARATUS, SYSTEMS, AND METHODS, filed Jun. 25, 2012, and U.S. Patent Application Ser. No. 61/663,617, entitled MODULAR BATTERY PACK APPARATUS, SYSTEMS, AND METHODS, INCLUDING VIRAL DATA AND/OR CODE TRANSFER, filed Jun. 25, 2012, may be coupled to a battery dock or shoe 3060 or other battery connection element. The battery may supply power to the portable inspection device through the shoe to power electronics, video cameras, such as camera 3010, wired or wireless transceivers, such as transceiver 3030, as well as other elements, such as a camera control unit (CCU) 3070, other wireless devices either in the portable inspection system or in other electronic computing devices, such as a second wireless transceiver 3020 as shown connected to the CCU 3070, and/or other components of the portable inspection system not shown in FIG. 30. In an exemplary embodiment, the wireless transceiver 3030 is a WiFi or other wireless LAN hub, node, or base station and is positioned in the cable storage drum, such as inside the cable storage drum hub, with the slip-ring connector 3067 used to provide electrical power and data signaling to the hub.

In operation, battery data may be provided from the battery 3050 through connection 3053 to the battery shoe 3060. The data may be passed directly through the shoe or may be modified by the shoe 3060 or other data format converter elements (not shown in FIG. 30) to reformat, change physical layer protocols, and the like, before being transferred through connection 3063 from the battery shoe 3060 to the wireless transceiver 3030 via an electrical connection (or optionally through other connections such as optical connections and/or wireless connections in alternate embodiments). Power may be supplied from the battery 3050 via power connection 3051 to shoe 3060, and then through electrical power connection 3061. Power may be further provided to camera 3010 and/or other devices through connection 3061(not shown).

A slip-ring connector 3067 may be used in exemplary embodiments to provide power to the transceiver 3030 and/or camera 3010 through the hub while allowing the hub to rotate relative to the housing, however, in other embodiments alternate data connection mechanisms or direct wiring may be used between the battery shoe and transceiver. In an exemplary embodiment, a three wire connection 3065 as shown may be used to transfer both data and power between the battery shoe 3060 and transceiver 3030. However, other numbers of conductors may be used in various embodiment to provide either serial or parallel data as well as DC power (e.g., as positive and negative leads). Likewise, in an exemplary embodiment the slip-ring may be a three conductor slip-ring connector, but in alternate embodiments may include more than three connection paths depending on the provided power and data signaling (e.g., in embodiments with more than one voltage power supply, multi-conductor data signaling, etc.).

Image, audio, and/or video data and related information may be transferred from the camera 3010 to the wireless transceiver 3030. The video may be compressed in the camera in a video compression module (not shown) to compressed formats such as MPEG4, H.264, and the like to reduce required transmission bandwidth. Video, audio, images, battery data, and/or other data or information may be transmitted wirelessly via connection 3021 from transceiver 3030 to another wireless node, such as to optional wireless transceiver module 3020 or to other wireless nodes, such as nodes on other external electronic computing devices 3080 such as portable or notebook computers, tablets, smart phones, and the like. In an exemplary embodiment, the CCU 3070 as shown may be replaced by functionality implemented on the external electronic computing device 3080, which may communicate wirelessly with transceiver 3030 to send and receive data, video, images, audio, control signaling, battery status and charge information, and the like. In embodiments where a CCU such as CCU 3070 is used, the CCU may receive battery data directly from the dock/shoe 3060 (connection not shown) and/or may receive data wirelessly from transceiver 3030 through transceiver 3020 or via other wired or wireless connections (not shown).

A data connection 3071 may be included between transceiver module 3020 and CCU 3070, which may be used to provide video data to a display, storage, and/or wired or wireless transmitter on the CCU for providing the data to external electronic computing devices and/or CCU 3070. The external computing device 3080 and/or CCU 3070, may also provide a display, such as on the LCD or other display device, of the received video, and may further provide a display of battery data or information provided from transceiver 3030, as well as other data or information generated by the portable inspection system. Audio from the camera 3010, and/or other audible outputs, such as battery status or charge level information, or other system information, may be provided by a speaker or headphone output of the CCU 3070 and/or external computing device 3080.

FIGS. 31-34 illustrate details of example embodiments of data transfer systems as may be used with various combinations of battery types (e.g., intelligent or non-intelligent or “dumb” batteries and corresponding battery docks/shoes). For example, FIG. 31 illustrates an embodiment 3100 of a three wire connection 3165 between a non-intelligent shoe 3160 having a portable intelligent battery 3050 connected to it. In this case, battery data is transferred from connection 3153 directly through the shoe (if a direct connection is available in the particular shoe in use) and then transferred, along with DC power via connections 3151 and 3161 to the optional slip-ring connection 3267, which may correspond with slip ring 3167 of FIG. 30 (or data may be transferred directly to a transceiver and/or other connected devices if no slip-ring is used). Embodiment 3100 assumes that the transceiver is configured to receive battery data in the format and protocol of the battery (e.g., a Lucid enabled or other intelligent battery data format). The other half of the slip ring connector 3167 may provide further connections of power and data to an intelligent (e.g., Lucid) compatible device) 3180, which may be a compatible wireless node such as transceiver 3030, and/or other components such as camera or other electronics or powered elements (not shown). Slip-ring connector 3167 may be a three conductor connector in an exemplary embodiment, but other connector types and configurations with different numbers of conductors may be used in various embodiments.

FIG. 32 illustrates an alternate embodiment 3200 of a three wire connection 3265 between a non-intelligent shoe 3160 having a portable intelligent battery 3050 connected to it. In this case, a serial interface module 3270, which is a protocol converter configured to convert battery data in a format such as the “Lucid” battery format described in U.S. patent application Ser. No. 13/532,721, entitled MODULAR BATTERY PACK APPARATUS, SYSTEMS, AND METHODS, filed Jun. 25, 2012, and U.S. Patent Application Ser. No. 61/663,617, entitled MODULAR BATTERY PACK APPARATUS, SYSTEMS, AND METHODS, INCLUDING VIRAL DATA AND/OR CODE TRANSFER, filed Jun. 25, 2012, to a format compatible with a standard input of the wireless transceiver, such as an I²C, SPI, CAN, or other serial or parallel interface. In this case, battery data is transferred from connection 3153, along with DC power via connections 3261 to the optional slip-ring connection 3267, which may correspond with slip ring 3167 of FIG. 30 (or data may be transferred directly to a device 3380, such as a camera or transceiver and/or other connected devices if no slip-ring is used). Converter 3270 may be placed on the other side of slip-ring connector 3167 in alternate embodiments.

Power may be passed directly through the converter 3270 and/or may be modified and provided via power connection 3261. The other half of the slip ring connector 3267 may provide further connections of power and data to an intelligent (e.g., Lucid compatible device) 3280, which may be a compatible wireless node such as transceiver 3030, and/or other components such as camera or other electronics or powered elements (not shown). Slip-ring connector 3267 may be a three conductor connector in an exemplary embodiment, but other connector types and configurations with different numbers of conductors may be used in various embodiments.

FIG. 33 illustrates another embodiment 3300 of a three wire connection 3365 between an intelligent shoe 3360 having a portable intelligent battery 3050 connected to it. This configuration is similar to that of FIG. 31, except that the shoe 3360 is an intelligent shoe and is capable of providing additional functionality, such as described in U.S. patent application Ser. No. 13/532,721, entitled MODULAR BATTERY PACK APPARATUS, SYSTEMS, AND METHODS, filed Jun. 25, 2012, and U.S. Patent Application Ser. No. 61/663,617, entitled MODULAR BATTERY PACK APPARATUS, SYSTEMS, AND METHODS, INCLUDING VIRAL DATA AND/OR CODE TRANSFER, filed Jun. 25, 2012, over that of a non-intelligent or “dumb shoe.” In this case, battery data is provide to the shoe 3360 through battery connection (e.g., contacts on battery and shoe) 3153. Data may then be provided via connection 3353 from the shoe, along with DC power via connections 3151 and 3361 to the optional slip-ring connection 3367 (or directly to a transceiver and/or other connected devices if no slip ring is used). The other half of the slip ring connector 3367 may provide further connections of power and data to an intelligent (e.g., Lucid compatible device) 3380, which may be a compatible wireless node such as transceiver 3030, and/or other components such as camera or other electronics or powered elements (not shown). Slip-ring connector 3367 may be a three conductor connector in an exemplary embodiment, but other connector types and configurations with different numbers of conductors may be used in various embodiments.

FIG. 34 illustrates yet another alternate embodiment 3400 of a three wire connection 3465 between an intelligent shoe 3460 (which may be same as shoe 3360) having a portable intelligent battery 3050 connected to it. In this case, a serial interface module 3470, which is a protocol converter configured to convert battery data in a format such as the “Lucid” battery format described in U.S. patent application Ser. No. 13/532,721, entitled MODULAR BATTERY PACK APPARATUS, SYSTEMS, AND METHODS, filed Jun. 25, 2012, and U.S. Patent Application Ser. No. 61/663,617, entitled MODULAR BATTERY PACK APPARATUS, SYSTEMS, AND METHODS, INCLUDING VIRAL DATA AND/OR CODE TRANSFER, filed Jun. 25, 2012, to a format compatible with a standard input of the wireless transceiver, such as an I²C, SPI, CAN, or other serial or parallel interface. In this case, battery data is transferred from connection 3453, along with DC power via connections 3461 to the optional slip-ring connection 3467, which may correspond with slip ring 3167 of FIG. 30 (or data may be transferred directly to a transceiver and/or other connected devices if no slip-ring is used). Converter 3470 may be placed on the other side of slip-ring connector 3467 in alternate embodiments.

Power may be passed directly through the converter 3470 and/or may be modified and provided via power connection 3461. The other half of the slip ring connector 3467 may provide further connections of power and data to an intelligent (e.g., Lucid compatible device) 3480, which may be a compatible wireless node such as transceiver 3030, and/or other components such as camera or other electronics or powered elements (not shown). Slip-ring connector 3467 may be a three conductor connector in an exemplary embodiment, but other connector types and configurations with different numbers of conductors may be used in various embodiments.

Battery data may be transferred from connection 3153 to connection 3353 to converter 3470, and then provided via connection 3453 to the slip ring and device 3480 (e.g., transceiver, camera, etc.).
